The present invention relates to an improved machine for papering theside wall and ceiling, and the purpose of the invention is to provide,in a machine of this kind a paste trough which will accommodate itselfto the paper as it passes between a paste applyingbrush and the roller,according to the angle of the machine relative to the side wall orceiling.

' Another purpose is to provide a machine, which applies the paper tothe wall, subsequent to the application of the paste, and afterwardssever the paper at a point according to the height of the Wall or thewidth of the ceiling.

Another purpose is to provide in amachine of this kind a handle having aspring tensioned pivotal joint with the frame of the machine, so thatthe handle may assume various positions relative to the frame as thepaper is being applied.

A further purpose is to provide a spring ten- 0 sioned roller cooperablewith the paper for retaining it in contact with the paste applyingbrush, which is mounted in the paste trough.

It is to be understood that the particulars herein given are in no waylimitative, and that while still keeping within the scope of theinvention, any desired modification of details and proportions may bemade in the construction of the appliance according to circumstances.

The invention comprises further features and i combination of parts tobe hereinafter set forth,

'35 of the frame of the machine in elevation, and

other parts of said frame in section.

Figure 6 discloses details of portions of the knife 51 and movablecutter 52.

Figure '7 is a detail view of one of the ears 9 .10, so that the sleevesmay be adjusted in differto show more clearly how a rod 10 may besupported in a bearing of the ear, for in turn to support a roll of wallpaper.

Referring to the drawings 1 identifies a frame of the wall paperingmachine, which may be constructed of any suitable metal preferably diedrawn or die stamped sheet metal, for example aluminum, and this framecomprises a body 2, a rear wall 3 and the opposite end walls 4. Theseend walls have diverging arms 5 and 6, in bearings of which rollers 7and 8 are mounted. The rollers 7 and 8 include a central rod, and a bodyof suitable composition, such as rubber, felt and fibre, such as willact to apply the paper to the wall. While the rollers 7 and 8 aredesigned to possess a proper hardness, they can not be too hard, such'as would result in an improper application of the paper to the wall.Either roll 7 or 8 may be used to roll the paper on the Wall, andthereby roll out any blisters or air pockets.

The body 2 of the frame is provided with lateral ears 9 at each end ofthe body, and journaled in bearings of the ears is a rod 10 for thesupport of a roll 11 of wall paper. The rod 10 removably fits in thebearing of one of the ears, while the other end of the rod is heldagainst movement in the bearing of the other ear 9 by means of a springholder 12. For instance the spring holder 'is fixed in any convenientmanner at 13 to one ent positions to accommodate wall paper rolls ofdifferent lengths.

Connecting the end walls 4 of the frame are guide rods 19 and 20, overwhich the wall paper 21 from the roll 11 passes. The end walls 4 of theframe have vertical slots 22, and mounted in the slots are the endportions of a rod 23, on which a roller 24 is carried. This roller 24preferably consists of a composition of rubber and felt, mostly felt,and the wall paper passes under the roller, which acts to keep the wallpaper in contact with a paste applying roller brush 25, which passesthrough openings of the end walls of a paste trough 26. That is to say arod 27 of the paste applying brush passes through the openings of theend walls of the trough and the ends of the rod 27 are journaled inbearings of the end walls 4 of the frame. Connected to the ends of therod 23 are coil springs 28, which in turn are fastened at 29 to theexterior of' the end walls 4 of the frame. By means of the springs 28the roller 24 is held in position to normally hold the wall paperagainst the roller brush 25. The upper ends of the slots 22 have offsetportions 30, which may receive the rod 23, when the roller 24 is raisedout of contact with the wall paper, so that the wall paper 21 may bepassed over the guide rods 20, when another piece of wall paper is to beapplied. I

The roller brush 25 rotates with the rod or shaft 27, and one end of therod 27 has a pulley 31, with which a belt 32 engages. The belt 32 inturn passes about a pulley 33 on one of the pintles of the roller 8, sothat when the roller 8 rotates by engaging with the wall paper androlling it on the wall 34 rotary motion is transmitted from the roller 8to the roller brush 25, through the medium of the belt 32. The belt 32is crossed as shown in Figure 3, so as to rotate the roller brush 25 inthe opposite direction to the roller 8, but in the same direction withthe passage of the wall paper under the roller 24. However, due to thepulley 31 being of a larger diameter than the pulley 33 the roller brushwill rotate slower than the roller 8, in which case the roller brushwill act to brush the paste on to the wall paper, which passes under theroller 24 at the same relative rate of speed as the rotation of theroller 8.

The paste trough 26, due to the rod 27 passing through openings in theend walls of the trough, oscillates on the rod, therefore: willaccommodate itself to the position of the frame, when the machine isused for applying wall paper on the wall or the ceiling. The fact is thepaste trough is provided with weights 35 at both ends, depending fromthe bottom of the trough, acting to balance the trough according to theposition of the machine. Suitable collars 36 are fixed on the rod 27 tohold the trough in position preventing endwise movement. Suitablecollars 36 are adjustably secured on the guide rods 19 and 20 by meansof set screws 37, said collars being provided for the purpose of guidingthe wall paper over the rods. vIt is obvious that the collars 36 can beadjusted according to the width of paper.

On the end of the rod or shaft 27 opposite the pulley 31, a secondpulley 38 .is mounted, and a belt 39 engages about the pulley 38 and inturn about a pulley 40 on one of the pintles of the roller ,7. The belt39 is. also crossed in order to impart movement to the roller-7 in thesame direction as the roller 8, that is to say when applying paper tothe ceiling.

In applying paper to the side Wall 34 of a room, the wall paper havingbeen engaged against the roller brush and over the guides 19 and 20, ispulled far enough through to lap it'over the roller 8, the paste. on thepaper acting to dampen the paper sufliciently to cause it to lightlyadhere to the surface of the roller, and when the machine is positionedas in Figure 1 so as to engage the roller 8 against the side Wall 34 thepaste covered surface of the paper will adhere to the surface of thewall, and then by moving the frame downwardly the roller 8 will roll thepaper flat against the surface of the wall, and since a handle 41ishingedly connected to the body 2 of the frame and capable of beingmoved outwardly, the machine can be operated on the full height of thewall 34.

In applying paper to the ceiling, the wallpaper is pulled sufficientlyunder the roller 24 and over the guides 19 and 20, then over the roller8, and then allowed to engage entire surface -of the roller 7. In thisinstance the machine is first placed which are pivoted at 58 to theinterior of the side in the opposite corner of the room, that is thecorner opposite but remote from the wall 34, in which instance themachine is drawn across the ceiling, the rollers 7 and 8 operating inthe direction of the arrows shown on Figure 1.

The hinge between the handle 41 and the body 2 of the frame comprises aheaded hinge pin 43, which engages through the ears 44 of the handle andthrough the ears 45 projecting from the bottom of the body 2 of theframe. A coil spring 46 is carried by the hinge pin 43, and ends of thespring engage at 47 and 48 with the body 2 and the upper end of thehandle 41, in order to so tension the spring as to retain a lug 49depending from the body 2 in engagement with a shoulder 50 on one of theears 44 of the handle, thereby holding the frame normally in an uprightposition relatively in alignment with the handle.

A severing mechanism comprising a stationary knife 51 and a movablecutter 52 is carried by the side wall of the frame. The movable cuttingknife is held in position by screws 53 passing through slots 54 of thecutter, and due to the slots the movable cutter has limited movement.The movable cutter has a saw tooth cutting edge 55, the teeth of whichare beveled, and is adapted to cooperate with the straight cutting edgeof the stationary knife 51. Normally the movable 'cutter 52 ispositioned with its saw teeth cutting edge spaced from the straightcutting edge of the knife 51, so that the wall paper may passtherebetween. When a strip of wall paper is applied to the wall 34 atfull height, the movable cutter is moved in the direction of thestationary cutter, the saw teeth piercing the paper and thereby severingit.

In order to operate the movable cutter links 56 pivotally depend fromthe cutter 52 and are in turn pivoted to the remote ends of the levers57,

wall of the frame of the machine. The adjacent ends of the levers 57 arein turn pivotally connected at 59 to the upper end of a link 60, whichpasses through the side wall of the frame. A spring 61, which is locatedbetween a collar 62 on the link 60 and the shoulder 63 of the side wallof the frame tensions to hold the link 60 in its uppermost position, inwhich case the movable cutter will be held normally in a downwardposition with the cutting edge of the cutter 32 spaced from the straightcutting edge of thestationary cutter, to permit of the passageof thewall paper between the edges. The link 60 in turn pivoted at64 to anoperating rod 65 mounted in suitable guides 66 of the handle 4. T

Obviously by pulling upon the rod 65 when the machine has reached thelower end of the wall 34 the movable cutter will operate to sever thepaper, regardless of what position the handle assumes with respect tothe frame, due to the 11.35 fact that the joint 64 is in close proximityto the hinge 43. The trough 26 has a cover 67 through an opening 68 ofwhich the bristles of the roller brush operate, thelongitudinal edges ofthe opening 68 acting to slightly engage with the endsof the bristles ofthe roller brush so that therewill not be too much paste transferredfrom the trough to the paper, just'enough to cause proper adherence ofthe paper to the wall.

The invention having been set forth, what is-1'45 claimed is: Y

at remote sides of the frame,-said'frame having a course for the wallpaper, a roller paste applying brush journaled in end walls of theframe, a tensioned roller constituting an element of said course forholding the paper yieldably against the brush to gauge the film of pasteon the paper, a weight balanced paste trough swung on the pintles of thebrush, whereby the paste gathered by the brush may be applied to thesurface of the paper traveling through the course, and means carried bythe frame for the support of a roll of wall paper, the paper from whichpasses through the course and is engaged with one or both of thepapering rolls, means operatively connecting the roller brush and thepapering rolls for transmitting revoluble movement from the latter tothe former, said frame having guide.

slots in its ends for the reception of pintles on the tensioned roller,said guide slots having offsets at their upper ends to receive thepintles to hold the tensioned roller in an inoperative position.
